Second of a planned series of mill studies to test the adequacy of a log grading system for species associated with ponderosa pine, the study reported was made with the cooperation of Stilwell-Pengilley Lumber Company, under the direction of a committee representing participating agencies, namely:

Improving existing and developing completely new products is an important part of maintaining a healthy business. This document outlines key principles of new product development, illustrated through the activities of a small sawmilling company.
For the sample of wide-ringed Douglas-fir discussed in this report, the relationship between specific gravity and percentage of summerwood is linear over a range of 16 to 60 percent summerwood content of the annual ring. The specific gravity of the summerwood and springwood portions of 96 dissected annual rings is...
In these tests, phenolic constituents from bark of Shasta red fir were found ineffective as stiffening agents for corrugating medium. Other means of application, however, may be effective.
Gum from inner bark of Shasta red fir was not so effective as a beater additive as was locust bean gum, but...
The amounts of treated wood present at a wood recycling center in western Oregon were surveyed over a 10-year period. Treated wood was found at 106 of 112 inspections, but the levels never exceeded 2 percent of the volume present. The amount of treated wood averaged 0.15 percent of the...
To directly determine mortality and predation in the endangered western Steller sea lion Eumetopias jubatus, we deployed implanted, satellite-linked post-mortem data transmitters in 21 juveniles. Data recovered from 4 of 5 detected mortalities exhibited precipitous drops in ambient temperatures followed by immediate onset of transmissions (N = 3), or gradual...
Satellite imagery of chlorophyll a concentration (chl a) provides the only holistic perspective
of productivity in marine ecosystems worldwide, yet its utility for understanding and
predicting the distribution of upper trophic-level predators remains equivocal. We tested the
hypothesis that remotely sensed chl a measurements spanning a decade can predict marine...

Forced-air drying of lumber is economically feasible as an aid to sawmills without dry kilns. Reduced cost of shipping more than offsets cost of drying with forced circulation of air. Investment in equipment is small.
In the Willamette Valley, forced-air drying probably can be accomplished successfully throughout the year. High...
The spruce budworm is an important enemy of the Douglas fir-true fir forests in Oregon. It can be successfully controlled by aerial spraying with DDT.
The influence of air temperature on spruce budworm growth, the growth of the host, and interrelationships between insect and host were studied on 15 areas...
